English abstract:
Radio Frequency Identification (RFID) systems
usually operate in a multiple RFID tag environment. If multiple
tags respond simultaneously, a collision occurs and the information
is discarded. In this paper, we propose a novel physical layer
collision recovery mechanism. We analyse theoretical limits of
the inventory time and show how our new method can approach
such theoretical maxima. We propose a method that resolves
more colliding tags by making collisions less destructive. In this
method a postprocessing of the received signal by beamforming
is performed. Furthermore, we investigate the influence of the
proposed method on the system performance by means of
simulations. We show that our method considerably shortens the
time necessary to interrogate tags.
